The average rate of change of a linear function is the slope of the line. Since we are given the following coordinates:
(0,150) and (3,0)
We can easily solve for the slope.
m = (y2 - y1) / (x2 - x1)
m = (0 - 150) / (3 - 0) = -50
Therefore, the average rate of change of the function in the three seconds is -50.
Answer to one im pretty sure is 136.4 degrees and to number 2 is a parallelogram (rectangle or square) you know because the side AD is equal to BC and AB is equal to DC
Answer:
50.40% probability that all 4 are different.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
Desired outcomes:
4 digits, all different
For the first digit, it can be any of them, so there are 10 possible
For the second digit, it can be any of them other than the first digit. So there are 9 possible.
For the third digit, it can be any of them, other than the first and the second. So there are 8 possible.
By the same logic, 7 possible digits for the fourth. So
![D = 10*9*8*7 = 5040](https://tex.z-dn.net/?f=D%20%3D%2010%2A9%2A8%2A7%20%3D%205040)
Total outcomes:
4 digits, each can be any of them(10 from 0 - 9).
So
![T = 10*10*10*10 = 10000](https://tex.z-dn.net/?f=T%20%3D%2010%2A10%2A10%2A10%20%3D%2010000)
Probability:
![p = \frac{D}{T} = \frac{5040}{10000} = 0.5040](https://tex.z-dn.net/?f=p%20%3D%20%5Cfrac%7BD%7D%7BT%7D%20%3D%20%5Cfrac%7B5040%7D%7B10000%7D%20%3D%200.5040)
50.40% probability that all 4 are different.
Can you see it ?
I hope the picture help !
Is there any other information lol
